The Prophet ﷺ had heightened devotion during the final ten nights of Ramadan
'A'isha (Allah be pleased with her) reported that when the last ten nights began Messenger of Allah ﷺ kept awake at night (for prayer and devotion), wakened his family, and prepared himself to observe prayer (with more vigour).
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْعَشْرُ أَحْيَا اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَجَدَّ وَشَدَّ الْمِئْزَرَ
